Eastern Front is a free mod for Company of Heroes. Following the ethos of mimicking a Relic Entertainment expansion pack, Eastern Front has succeeded in adding two full new factions, the Soviet Red Army and the German Ostheer, packed with unique and exciting units to the existing armies - a feat never before achieved in the Company of Heroes world.

LOL, it remind me of the Teutonic knights' crusade in the same region where the Eastern Front battles were fought.
In fact, the Soviets did made a propaganda poster mentioning about this rather delicate part of Russian/German history. The most famous quote on that is "We beat them(Germans) before", not exact translation, but you get what they means.
